What happen in the boiling water on the kettle?
Materials can come in three phases, depending on physical conditions. They are gas, liquid, and solid. If you boil a kettle of water, you are first heating up the liquid water inside the kettle. But then at boiling temperature (which is about 100 deg C or 212 deg F) the liquid in the kettle starts to turn into gas, which we call steam. As a gas, that steam rises to the surface and that's when you start to see the bubbles we call boiling. So when we "boil a kettle" we are creating steam that creates the boiling bubbles.
